Question

我正试图在Ionic的Twitter上更新或发布状态。我使用ngCordova.it做了oauth工作正常，以获得UserProfile Api。但是当我尝试发布图像或状态时，它会出错（“无法验证您”）。请在此处查看我的代码。

    var services = angular.module('twitter.service', [])
    services.factory('TwitterLoginFactory', function($http, $cordovaOauthUtility, $cordovaOauth, $state) {

    window.localStorage.setItem(twitterUserProfile, JSON.stringify(data));
}
/** Get  Twitter User Profile in Local Storage**/
function getStoredTwitterProfile() {
    return window.localStorage.getItem(twitterUserProfile);
}
/** Store Twitter access_token in Local Storage**/
function storeTwitterToken(data) {
    window.localStorage.setItem(twitterKey, JSON.stringify(data));
}
/** Get Twitter access_token in Local Storage**/
function getStoredTwitterToken() {
    return window.localStorage.getItem(twitterKey);
}

function convertImgToBase64URL(url, callback, outputFormat) {
    var img = new Image();
    img.crossOrigin = 'Anonymous';
    img.onload = function() {
        var canvas = document.createElement('CANVAS'),
            ctx = canvas.getContext('2d'),
            dataURL;
        canvas.height = this.height;
        canvas.width = this.width;
        ctx.drawImage(this, 0, 0);
        dataURL = canvas.toDataURL(outputFormat);
        callback(dataURL);
        canvas = null;
    };
    img.src = url;
